Medicine Astronauts' blood shows signs of DNA mutations due to spaceflight

I debated choosing the Outer Space flair or Medicine: and felt the impact of their space travel may affect their health at some point due to the space flights:

Astronaut cancer risk needs careful monitoring, concludes a study that stored spaceflyer blood for 20 years.

All fourteen astronauts in the study, from NASA's space shuttle program, had DNA mutations in blood-forming stem cells, a Nature Communications Biology study (opens in new tab) Aug. 31 concluded. The mutations, though unusually high considering the astronauts' age, was below a key threshold of concern, however.

While the study is unique for keeping astronaut blood around for so long, the results are not show-stopping. Rather, the researchers suggest that astronauts should be subject to periodic blood screening to keep an eye on possible mutations. (And it should be considered in context; another 2019 study, for example, found that astronauts are not dying from cancer due to ionizing space radiation.)

Good article but then they threw in this gem:

NASA recently changed its lifetime radiation requirements for astronauts that critics said were discriminating against women, who historically had lower limits than male astronauts. (To date, other genders have not been disclosed in the agency population.)

Hands up all those who immediately thought of The Quatermass Xperiment.

Fantastic

Mutant astronauts!! The future is promising.

Maybe one of them will eventually mutate the mythical spegg that proves us all wrong.

But what about the trans astronauts?
